The "Good" AI is only allowed to draw human attention to an issue - it cannot act, and the humans fundamentally have to (a) figure out what the issue even IS and (b) how to resolve it, basically entirely on their own. Humanity is fundamentally still in charge, the AI just occasionally nudges us to look in the right direction.
Conversely, the "Evil" AI is allowed to do whatever it wants - humanity is no longer in the loop.
And, indeed, the show goes further: they might very well be considered equally moral from some sort of Utilitarian 10,000-foot view. The "Evil" AI wants to save Africa from poverty and pestilence while the "Good" AI is helpless to act on that scale. The moral difference comes down almost entirely to the idea of "minimal intervention" vs "radical revolution"
